IMPROVEMENT IN ELASTIC-FABRIC MATTRES-FRAMES.

Specification forming part of Letters Patent No. 142,827, datedSeptember 16, 1873; application filed April 4, 1873.

To all whom it may concern:

Be it known that we, JOHN E. WHI'ITLE- star and J. WILLIAM G. PETERS, ofChicago, in the county of Cook and State of Illinois, have inventedcertain Improvements in Elastic-Fabric Mattress-Frames, of which thefollowing is a specification:

This invention relates to certain improvements in the means forstretching the wovenwire web or its equivalent in mattresses; and theinvention consists, particularly, in combination with the end and siderails of the mattress frame, of metallic plates attached rigidly to theend rail, and clasping the sides of the side rails, but having noflanges at the top or bottom.

Said plates are made with horizontal slots, through which two bolts arepassed to clamp them laterally against the side rails, and

which said plates are furnished with setscrews, setting against the endsof the side rails, to adjust the end rails with and vary the tension ofthe fabric.

In applying theweb or fabric to the frame one of the clamping-bolts isremoved from its slot, and the metallic plates, with the end railattached, are lifted upon the other bolt as upon a pivot. The web orfabric is then applied to the end rail and said end rail pressed down toplace, whereby the greater portion of the slack is taken up. The otherbolt is then inserted, the remainder of the slack of the web or fabricbeing then easily taken up by the setscrews before the clampin g-boltsare tightened.

By this construction of plates there is combined the advantage ofrapidly taking up the slack at the start by a pivoted clamp, with thefacility of a further adj ustability by means of the set-screws or othermeans.

In the accompanying drawing, which forms a part of this specification,Figure 1 is a side elevation of this invention attached to a portion ofthe frame. Fig. 2 is a bottom view of the same, and Fig. 3 is an endview thereof taken from the left of Fig. 1.

Like letters of reference made use of in the several figures indicatelike parts.

To enable those skilled in the art to make and use this invention, wewill proceed to describe the same with particularity, making use in sodoing of the aforesaid drawings by letters of reference thereto.

In the said drawings, A represents one of the side rails of a commonwoven-Wire mattress-frame, and B is the adjustable end rail, to which isattached the web of wire or other fabric, indicated by the line 0 inFig. 1. D

D are metallic plates, setting fiat against both sides of the side railA, and attached to the end rail B by screws or rivets b, or otherwise.These plates D, or one of them, are continued across the end to form anend plate, E, through which screws the set screw. F, bearing against theend of the side rail A. The plates D D are each provided with twohorizontal slots, G G, one placed above and behind the other. H H arebolts passing through the slots G G and through the rail A, beingsecured by nuts h h, serving to clamp the plates D against the rail.

When the elastic woven-wire webbing G or other fabric is to be applied,the bolt H is removed, leaving the bolt H to act as a pivot. The endrail is then lifted, lifting with it the plates, as is indicated bydotted lines at Fig. 1 of the drawing, the whole rising upon the bolt Has a pivot. The webbing or other fabric is then applied and secured tothe end rail,which is then brought down to its proper place, strainingthe webbing, in so doing, enough to take out all the slack. The boltH isnow inserted and the set-screw F brought in play to complete thestraining. The nuts h h are then tightened and set, and the operation iscomplete.

If, in course of use, the web or other fabric becomes slack, or adifferent degree of tension is desired, it may be adjusted by theset-screws F at any time.

The outer plate of each pair is attached to the end rail at the end, notextending so far out as the attachment of the inner plate to the saidrail, so that the corners of the end rail may be cut away or rounded, asat M, to fit round-cornered bedsteads. An elastic sur face extending thewhole length of the bed is thus obtained.

After having thus fully described the construction and operation of theinvention, that 2. The combination of the flat side plates D,

made with slots G G, the bolts H H, and rails which we deem new, anddesire to secure by A B, substantially as specified. Letters Patent, is-

1. The combination of the end plate E, furnished with the set-screw F,the side plates D, made with slots G G, the bolts H H, and rails A 13,substantially as specified.
